UNITED STATES ADOLPH WEBER,

PATENT OEEICE.

OF DETROIT, MICHIGAN, ASSIGNOR TO HIMSELF AND LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 256,609, dated April 18, 1882.

` Application ined January 11,1882. (No moda.)

To all lwhom it may concern:

Be it known that I, ADOLPH WEBER, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Lubricators;l and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, which forms a partotthis specification.

The nature of my invention relates to certain new and useful improvements in that class ot' lubricators for steam machinery known as displacement-lubricators,77 or those wherein the oil is displaced and forced out of the de vice by the condensation of the steam.

The object ot' my invention is to provide such a device which will deliver the oil in certain quantities, such quantities being variable at pleasure, without the employment of valves to regulate the tiow, hy means ofa condensingchamber, which maybe enlarged or diminished at will by the turning of a knob attached to a threaded stem projecting above the body of the device.

The invention consists in the peculiar construction and operation ot' parts and their coinbination, as more fully hereinafter described.

In the aeco'ml'ianying drawing, which shows an elevation partly in vertical central section of my improved lubricator, A represents the' oil-chamber proper, into the bottom of which is screwed the plug B, by means of which connection is made to the steam-pipe, or the part to be lubricated. This plug is hollow and provided with a valve, O, to regulate the flow of steam through the plug and pipe D, with which` said plug is connected. This pipe D communicates with the pipe D', which projects into the chamberA nearly to its top, as shown. E is another hollow plug and internally provided with a coarse thread, and this plug is screwed into the top of the chamber immediately above the end of the tube D.

F is .an inverted chamber, the bottom being open, while the top is secured to the lower end of the stem Gr. The upper part of this. chamber is provided-'with a coarse thread to engage with the female thread in the plug E, and the knob H enables the operator to turn the stem at will and withease.

I is a nxed guide secured to the neck of the plug E, and J is an L-shaped index sleeved upon the stern just below the knob in'such a manner as not to lturn with the stem, but to follow its vertical motion. This index is provided on its outer vertical face with a series of notches, and it passes' through a slot in the overhanging end a of the guide.

M is a discharge-cock, through which the I contents of the chamber A may be drawn ot when desired, and N is a plug closing an opening through which oil is filled into said chamber.

In practice, the device being ready for use,

the oil in the chamber stands upon the level of the top ot the Atube D. Now, if a small supply otl oil is wanted to overlow through said tube, the stem G is screwed down, carrying with it the chamber F, which enters the oil and embraces the top ot' the tube D. The valve() is then opened and steam tiows through tube D into the chamber F, which is now of a very small area for condensing purposes. Hence the condensation will be slow, and the water of condensation will drop into the oilchamber'slowly, and displacing drop by drop a like quantity of oil, which escapes down through the tube. To increase the outtiow it is only necessary to raise the chamber F by means of its screwstem, thereby affording more room for condensation. The index above described will show the vcapacity of the condensing-chamber at all times.

that I claim as my invention is c 1. The pipe D, having valve-seat and plug B, formed of one casting, and having a channel connecting with pipe D', combined with the valve C, vessel A, condensing-chamber F, land means for raising and lowering the same at will, as and for the purpose specitied.

2. The vessel A, having inlet-aperture N, the plug B, having channel connecting with pipe D', the pipe D, and valve-seat, the valve G, the outlet m through the plug B, the condensing-chamber F, and means for adjusting its capacity at will, combined with means, I J, for indicating said capacity, all as and for the purposes set forth.

ADOLPH WEBER. Witnesses:
